Nick, > Can you clarify what you mean by 'java loader' and 'hosted mode'?
My java loader is a servlet which loads a CSV from disk, processes it and persists entities to the datastore. The CSV has the values for the properties I want my entity to have. The CSV and the data it points to is in WEB-INF, so I can get away with loading large sets in hosted mode and smaller sets in production (because of the static file limit and request timeout it is not possible to load all of my data in production using this method). The Kind is created when I persist that first entity. This is functionally similar to a python bulk loader, except it is a one-off servlet, and does not come with all of the configuration and transport mechanism options that provided by the python SDK. > In the Python SDK, entities are named after the unqualified name of the class, by default - so a 'Film' gets loaded with an entity name of 'Film'. You can specify a custom entity type name with the kind() method. I'm still not hugely familiar with Java, so I'm not sure under which conditions it will use qualified and unqualified names - basically, you need to match those with your Python loaders. At one point I tried to convince bulkloader.py (using --kind=package.MyClass) and my custom bulk loader (bulkloader.Loader.__init__(self, 'package.MyClass')) to accept the full java package name, but even when I used namespaces in the python model, this did not work. Perhaps a python example for the kind() method you mention? Am I correct in assuming that I should provide a kind() method in my custom bulk loader which overrides the default in much the same way as handle_entity() or generate_key() gives you a hook into those functions? In other words, should I try this? ================================ class MyClass(db.Model): name = db.StringProperty() other_property = db.StringProperty() class MyClass(bulkloader.Loader): def __init__(self): bulkloader.Loader.__init__(self, 'MyClass', [('name', str), ('other_property', str) ]) def kind(self, entity): return 'package.MyClass' ================================ I understand if you can't provide a Java example, no worries. In lieu of that, could you provide a full example of customizing the python model's namespace using the kind() method in a custom bulkloader, along with the command line syntax to push it (with appcfg.py using the custom loader). And if that's not enough <grin> it would be good to see the query syntax in the runtime application (e.g. "SELECT * from package.MyName" with the right python import statements).
